Blend with an immersion blender until smooth.
Toss with pasta and serve with sausage meatballs.
Top with a little more freshly grated parmesan cheese.
Notes
An immersion blender makes this sauce super smooth and creamy. If you don’t have one, you can also use a whisk.I used homemade pumpkin puree, but you can easily use canned, store-bought pumpkin.The cinnamon adds such lovely and subtle warm notes to this recipe. You could also add a touch of fresh nutmeg, as it pairs well with creamy sauces and adds another layer of warmth to the dish.
